what is user mode & kernel mode?

Answer Posted / nishikant sahu

The term “context Switching” is used to define the user mode
and kernel mode.

that become kernel mode and if not then it a user mode.
context Switching.. Save the current state of program and
execute the other task.
Suppose in your program if system calls happen then it
should be executed by Kernel so this time “state of the
process” should
Be saved and move to kernel mode.
